Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018472, here are decompositions:
- 43 + 1018429 = 1018472
- 61 + 1018411 = 1018472
- 163 + 1018309 = 1018472
- 181 + 1018291 = 1018472
- 271 + 1018201 = 1018472
- 349 + 1018123 = 1018472
- 613 + 1017859 = 1018472
- 673 + 1017799 = 1018472
Showing the first eight; more decompositions exist.
